Best Practices Guidelines for Self-Consolidating Concrete

Best Practices Guidelines for Self-Consolidating Concrete 3 WHAT IS SELF-CONSOLIDATING CONCRETE? Self-Consolidating Concrete VSI values of 0 or 1 indicate acceptable SCC. VSI values of 3 clearly indicate SCC that should be rejected. VSI values of 2 indicate that the concrete is unstable and the mix design should be immediately modified to obtain a VSI value of 0 or 1 (i.e. site addition of

The American Concrete Institute (ACI) defines self-consolidating concrete (SCC) as “highly flowable, nonsegregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation.”

CIP 37 Self Consolidating Concrete (SCC)

Self consolidating concrete (SCC), also known as self compacting concrete, is a highly flowable, non-segre-gating concrete that can spread into place, fill the formwork and encapsulate the reinforcement without any mechanical consolidation. The flowability of SCC is measured in terms of spread when using a modified version of the slump test (ASTM C 143). The spread (slump flow) of SCC

Self-Compacting Concrete Applications and Advantages

The concrete mix of SCC must be placed at a relatively higher velocity than that of regular concrete. Self-compacting concrete has been placed at heights taller than 5 meters without aggregate segregation. It can also be used in areas with normal and congested reinforcement, with aggregates as large as 2 inches.

What is the SCC in concrete mix? Quora

SCC stands for self-consolidating concrete or self-compacting concrete. Another term is flowable fill or lean concrete. A typical concrete mix might be a 5-sack mix with five 94-lb sacks of cement per cubic yard. Flowable fill (lean concrete or SCC) is about 1 sack of cement per cubic yard. So strength-wise, mixes I have worked with are about 300 psi compressive strength or like hard dirt. We
